This invention comprises improvements in or relating to knitted fabrics and the production thereof, and has for its main object the production of a fabric in which the tendency-toorpossibility of laddering, running or raveling 1s llllllllnlZGCl or eliminated.

1 According to the present invention a fab-. ric is provided composed of or embodying knitted stitches wherein lockor tie is 0 formed by a thread bar extending between successively for-med stitch loops and also constituting one of the inter-meshing loops of a subsequently formed stitch.

In a knitted fabric composed of alternate needle and sinker wales a bar of thread eX tending between successively formed stitch loops may in accordance with this invention be formed into a loop and threaded through a stitch loop located in one of the needle wales next alongside of the sinker Wale from which said bar loop is drawn so as to constitute part of a locked or tied stitch in the said needle Wale.

For the purpose of more fully describing the nature of this invention reference will now be made to the accompanying drawings,

6 tending between two successively formed,

stitch loops. The phrases loop and stitch are given their normal significance.

One embodiment of the invention (Figures 1 and 2) will now be described as applied, byway of example, to what is customarily known as plain hosiery fabric.

Thread 1 constituting a sinker bar ex tending between or connecting two adjacent stitches 2 on a horizontal course is taken in the form of a loop and passed through a stitch 3 1n a subsequent course orrow, con- Figure 3 the tiedor locked stitches are in each needle Wale, whlle 1n F1gure 4 such veniently j the next course, the stitch 3 through which saidloop is threaded being advantageously in the same vertical row or Wale as that containing either of the two stitches 2 from between which the f loop 1 is drawnzy A stitch at ofa further subsequent course is now caused to pass through the closed end ofthe aforesaid loop 1 subsequently to passing said loop through the firstnamedstitch 3, and the closed end of 5 the loop 1 thus becomes a virtual additional stitch in the wale in which it is located, i. e.

a normal needle stitch,while the stitch 3 which passes over or encircles the loop 1 constitutes a tie or knot on said loop which auytension orpull onthefabric will tend to tighten. i t 1 Groupsof stitches with a'knot ortie as above may be produced in succession, one

group immediately following another, in 7 which case theportlon of the closed loop extending. beyond the knot or tie may constitutethe commencementof the next group.

The knotted or tied stitches may, however, bespacedby any desired number or type of 7 stitches. i J i. 1

i In Figures 3 and 4 thesinker bar loops 1 arereach threaded through a stitch loop 2 .appertainingto the same-knitted course as that from which the bar loop 1 is drawn, in which casethe loops 1 function as stitch loops in the course or rownext succeeding that from which said loop is drawn.. In

stitches. are produced in alternate needle wales, th s bemg determined by the method of transferring the bar loops 1 to the needles.

Iuproducing locked fabric as shown in any of the figures previously described the bar loops 1 which are drawn from between adjacent stitch loops are each retained on any suitable p1 cker needle or equivalent retaining element while one or more subse- \quent courses are knitted upon the needles of the machine, after which the loop 1 which is retained by said picker, needle or its equivalent is transferred into the hook of an adjacent needle. Prior to said transference being effected, however, the stitch loop. 3

previously existing on the shank of the needle is cleared and after said transference has been effected the said cleared stitch loop 3 is knocked over so that the bar loop 1 becomes in effect a new stitch loop while the cleared loop 3 which is knocked over encircles the loop 1 and forms a locking loop. The thread subsequently fed to the needles is then drawn through the transferred bar loop 1 in the normal manner.

The transferring of the loop from the picker or the like to the needle may be accomplished by any known or approved transferring means. For example, the picker may be displaced laterally or diagonally so as to cause the needle to rise within the loop carried thereby, or said transferring element may be so cranked or shaped as to shog the loop carried thereby laterally by longitudinal or endwise movement of said element.

In a further alternative arrangement one or more stitches may be formed on or by the thread constituting the sides of the drawn bar or sinker loop, the closed end of said loop subsequently having a further stitch drawn therethrough.

I claim 1. A knitted fabric composed of alternate needle and sinker wales and wherein a thread portion constituting a sinker bar is surround the drawn thread bar loop and becomes part of a locked or tied stitch, said drawn bar loop forming in effect an additional stitch loop in the Wale in which it is located.

5. A method of producing knitted fabric which consists in drawing a loop from a thread bar extending between stitch loops in a given course appertaining to needle wales located next alongside each other, passing the said drawn loop through a stitch loop in one of said needle wales in a subsequently knitted course and casting-off said stitch loop so that the said drawn thread loop constitutes in effect an additional stitch loop in the Wale in which it is located.

6. A knitted fabric wherein a thread bar extending between and forming a connection between the stitch loops in two stitch wales located next alongside each other is drawn in the form of a loop through a subsequently-formed stitch loop in one of said wales, the latter loop'being cast off around the extended bar loop to form a lock or tie thereon.

A knitted fabric wherein a thread bar which extends between two successivelyformed stitches in the same course appertaining to stitch wales located next alongside each other in the fabric is formed into a loop and passed through a stitch loop in a subsequently knitted course or row, a stitch loop in a further subsequently knitted course or row being then passed through the closed end of the first-named bar loop, which loop thus becomes part of a locked or tied stitch.

3. A knitted fabric wherein a thread bar loop taken from between successively formed stitches in a course or row of stitches is passed through a stitch loop appertaining to the knitted course or row from which said bar loop is taken, a stitch loop in a subsequently knitted course being then passed through the closed end of the said bar loop which loop thus becomes part of a locked or tied stitch.
